Ninety nine years since Faberge made its last Imperial egg, for Tsar Nicholas II, the famous jewel maker will show off its newest creation at an exhibition of watches and jewellery in Doha.

The "Faberge Pearl Egg" features 139 fine white pearls, and more than 3,300 diamonds as well as other precious gemstones, according to the jeweller.

Several Gulf nations have a long history of pearl diving, and Qatar is building an artificial island off its coast named after the precious treasure.

The egg is the first of its kind commissioned since World War I. The egg has been commissioned in association with the Gulf-based Al Fardan jewellery group, which is renowned for its pearls.

The USD two million price tag may end up being a conservative estimate. The last Imperial egg to be auctioned reportedly went for more than USD 30 million when sold last year after being found in a jumble sale.

The last officially known price for an egg was USD 18.5 million, which was sold at Christie's in London in 2007.

Faberge says that 50 eggs in total were commissioned and 43 of those are known to have survived the Russian Revolution.
